f 26 January 1998 AGE-NC Project No. 97-0394 Page 2 of 4 3.0. 'SCOPE OF WORK 3.1. PROBING AND SAMPLING A subsurface investigation at the site is necessary to determine if hydrocarbon-impacted soil is present at the site. Initially, AGE proposes to advance four(4) soil probe borings at the site. Probe borings will be advanced to depths of approximately 25 feet, using direct push technology (DPT). Proposed probe boring locations are illustrated in Figure 2. Soil samples will be collected at five-foot intervals using a Geoprobe sampler and four brass sleeves. Upon sample retrieval,the second brass sleeve will be removed from the sampler. The ends of the sleeve will be immediately covered with Teflon tape or aluminum sheets, capped and sealed with tape. Each sample will be placed in a chilled container for transportation to a State-certified laboratory. Each sample sleeve will be labeled with the following: boring location,depth,time, date . and sampler's initials. After collection, samples will be stored'in a chilled container and transported to a State-certified laboratory. 3.2. EQUIPMENT DECONTAMINATION All sampling tools and brass sleeves used for sample collection will be thoroughly rinsed with clean water after washing with a solution of Aiconox. All Geoprobe rods are cleaned prior to advancement in each probing location. 3.3. LABORATORY ANALYSIS Selected soil samples will be analyzed by the following EPA methods for the specified analytes and compounds; • EPA Method 8015 M for total petroleum hydrocarbons quantified as gasoline (TPH-g), • EPA Method 8020 for volatile aromatic compounds (benzene, toluene, ethyl-benzene and total xylenes: BTE&X), • and if field observations indicate that other petroleum hydrocarbons are present, additional analysis may be necessary. Laboratory reports of both soil and ground water analyses, testing methods, laboratory quality assurance/quality control (QA/QC) reports, and sample chain of custody documentation will be presented in a report with the findings and recommendations.
